I have about 3/4 gallon of fuel that's been stored in the tin container it came in in a cabinet in my garage (completely out of sunlight) for about a year and a half. I'm in southern California so the temperature is a pretty constant 50-70 in my garage year round. I plan to get back into nitro soon, and I'm wondering if you think there's a good chance of the fuel being bad, and if I do run it will it cause engine damage or just not run properly?
